`.imputation filed october 2,1926. serial 119,139,150.

VThis invention has reference to a nozzle designed forspraying water into the ashpit of a furnace to la Y the dust and prevent the dust from passing'into the room in which the furnace is positioned, while the ashes` are being removed.

An object of the invention is the provisionv proceeds, the .invention Vresides in thelcom-v binatlon and arrangement of parts and 1n the details of construction hereinafter described andy claimed, it being understood that changes in the precise embodiment .of

the invention herein disclosed,may be made within the scope of what is claimed, without departing from lthe spirit` of the invention.

Referrng to the drawing: i

Figure 1 is a sectional view taken on line 1-1 of Figure 2.

Figure 2 is a fragmental elevational view of a furnace equipped with a` device constructed in accordance with the invention.

Figure 3 is an elevational view of a nozzle.

Figure 4 is a longitudinal sectional view therethrough.

Referring to thedrawing in detail, the reference character 5 indicates the front of a furnace whichis supplied with the usual fire door and ashpit door, the ashpit door which carries-the nozzle forming the present invention being indicated by the reference character 6 and supported by the hinges 7.

The lreference character 8 indicates the supply pipe to the boiler and to which theV pipe 9 is connected, the pipe 9 being supplied with a` valve housing 10 in which the valve l 11 is positioned, the valve 11 controlling the passage of fluid through the pipe 9.

Communicating with the pipe 9 is a pipe 12 that is connected with the pipe 13, through the elbows 14 and 15, there being a substantially short pipe section 16 between the elbows 14 and 15', and-withwhich the elbow has'swivel connection.

The reference character 17 indicates a depending pipe connected with the pipe 13 to the elbow 18, which pipe 17 connects with the pipe 19 through the elbow 20. Thispipe 19 extends through an opening formed 1n end portion 26 provided with a head 27.

one wall of the ashpit door 6 and has an inwardly extended end portion 21 carrying the nozzle 22, to the end that when the door is swung to its open position, the nozzle and communicating pipe will be swung to a position remote from the ashpit door to allow easy access thereto forthe removal of the ashes vcontained therein.

The nozzle ,forming the invention includes a bodyportion having av threaded extremity 23 so that it may be securedwithin one end of a pipe, the nozzle having internal threads 24 to receive the threaded extension of the core 25, which core has a reduced yOwing to the construction of the reduced portion 26, it will be seen that a space. is

provided between the core and inner wall of the body portion defining a passageway to allow fluid to pass from the valve body. A bore 28 is formed in the core and extends Y to a` point substantially intermediate the ends thereof so that it communicates with the transverse bore 29 that in turn communicates with the passageway between the body portion of the nozzle andreduced portion 26 thereof.

As clearly shown by Figure 4, the head 27 is disposed within the contines of a flange 30 which has a substantially short lower side and a. substantially wide upper side to the end that the uid vwill be directed downwardly and not against the grate bars.

Lateral openings 31 are formed between the flanges to allow the fluid to pass laterally from the nozzle.

From the foregoing it'will be obvious that when it is desired to dampen or wet the ashes to lay the dust thereof, it is only necessary to operate the valve member 11 to cause fluid to pass through the nozzle and onto the ashes contained in the ashpit.

After the ashes have been sufiiciently moistened, thev door may be swung open, moving thenozzle and communicating pipes to a point remote from the ashpitdoor open-l ing so that thev ashes may be readily removed.

I claim:

A nozzle havinga tubular body with two forwardly projecting curved flanges of unequal extent in the axial direction of said body, said flangesoooperating to partially define an enlarged continuation of the bore of said body, lsaid flanges being spaced to o inner end of said'core being tubular with 10 lateral outlets leading to the yspace between said core and the Wall ofthe borethru said body.

In testimony that I Claim the foregoing 'es my own, I have hereto affixed iny'sig- 15 nature. f
